So this guy that my girlfriend was with (Nate) keeps calling her and asking and if he can come over. She knows I'm with her and even says I don't have to know. I tried to let it go but I finally told him stuff and he told me what he did with her and asking me what his dick tastes like. I asked her once if anyone slept in her room when I slept over once at her house ( we always sleep at my house) and she said no. This guy Nate perfectly described her room and how to get to it. It bothers me that she's slept with people while I've only slept with her. I don't want to be in this relationship anymore.
